CONCRETE APPARATUS.

Specification of Letters Patent.

To all whom, t may concern: a p

Be it known that I, ALBERT Gr. HIGGINS, a citizen ofthe United States', residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Concrete Apparatus, of whichl the following. is. a specification. I

This invention relates to concrete apparatus of that class whereby concrete is ap-V plied to an object b rojectin ita ainst thesame with. consiheable forgcre, arid has for its object to produce means for both mixing and depositing concrete under centrifugal force or for 4subservi'ng either of said functions, it being understood that the term concrete isA employed in its generic sense, .that is, is intended toembrace any plastic mixture which willadhere to the object on 'which it is deposited and harden as it dries.

Wit'hthis general. object in view the invention consists of certain novel and peculiar features Qf construction and organization as hereinafter described and claimed; and in4 order that it may be fully understood reference istol be had to the accompanying drawings, in which Figure 1-, isa side view cfa concrete mixing; and applying machineembedyingf my invention. Fig. 2, is a central vertical section of'th same. Fig. 3, isv asimilar section'l` of ai modified form ofconstruction.V Fig, 4s, isan irregular .section taken on the line IV-l-V of Fig. l.' Fig.` 5, is. an` enlarged section taken ontheline V-V of4 Figil.

. the said drawings where-like reference characters identify correspondingr parts, l

is a circular easing. consisting of two disks2f spaced apart', and :provided perrpherally with inwardly-projecting flanges?)` spaced apart to form an interposed open1ng4 anda second or feed opening 5'. Around the periphery of the disks are suitable outwardlyprojecting ears 6 connected by cross' bolts-ff?v whereby the'disks are secured in rigid relation with the inner edges of'their flanges.V

clampedtightly together..

To vary Vthe size of discharge opening. 4

and to permit the discharge to occur through said opening at different points so that the plastic material may be discharged 'in the desired direction,- :lling plates' 8 are fitted,

adjustably between the disks in saidopening 4, and said plates are provided with outwardly-projecting flanges 9 to lit agalnst the peripheries of the disks so that they can not slip inward from their proper position, as

said plates are curved to correspond with the curvature of the flanges 3 and their inner surfaces must be disposed in the circular plane of the inner surfaces of said flanges, as shown clearly in Figs. 2 and 3', it being understood that these plates are longitudinally adjustable and are clamped rigidly at the desired pointof adjustmentl by the adjacent bolts 7, as the sides of the casing will yield sufficiently to effect such clamping of the plates between the sides or disks of the casing, and in this-connection it is to be understood that the end of the liange 3 to the right plates are beveled as shown at 10,11 and l2 respectively, for a purpose which` hereinafter i appears.v

13 a cylindricalconveyer casing communicating at its lower or discharge end with feedopening 5 and 141 -is ahopper for supplying properly mixed and proportioned sand and cement to the upper endof theconveyer casing, Preferably the casing 13 and' hopper 141V will be cast @integral with eachother and the casing, that is to say, will consist of halves, each half being formed integrally with one-half of the casing, and

will be bolted together as at 15. If desired a supplying hopper. 16 will be .arranged as shown to discharge "into hopper 14.

v Arranged withinand substantially filling the; casing is a circular brush 17l having steel or otherv stiff bristles,- and said brush is secu-red rigidly u-pon a shaft-18 by clamp-l ing collars 1-9, and the shaft i-'s preferably journaled in ball-bearings 2()4 secured in openings 21 inthe `disks or sides of the casing. M'ounted o-n one end of the shaft ad Patented J une 24, 1913.

jacent to the casingris a belt wheel- 22 envgaged by a drive belt 23 which is Aadapted to revolve the bruslr in the direction indicated by the arrows.. At one end of the 'shaft is formedVv a wormx threadI 24, meshing with a worm-*wheel* 25l secured on the-'lower end of a shaft 26, and said worm threadand `-worm wheel are preferably inclosed by a vhousing 27. The shaft 26 is suitably )ournaledand isprovided at its. upper end with a gear wheel 28 meshing-with -a gear wheel 29 -on the lowerend of a second suit-ably journaled shaft 30, and-said shaft is providedwithI a gear wheel 31 meshing witha gear wheel' 32 on the upper portion of the shaft-33 of. a spiral lconveyer 34 arranged 1n the --conveyer casing' 13 for feedlng at' a 70 of plates 8 and the left-hand ends' of said Y i predetermined speed and at predetermined quantity, mixed sand and cement through said feed opening and against the periphthe duplicate parts bein-g numbered 37 and 38, and arranged yin the casing 37 is a reversely turned spiral conveyer 39 with its shaft 40 geared to shaftBS at 41 so that the conveyers shall be simultaneouslybperated, the smaller conveyer 38 preferably supplying cement and thehopper 14 sand to the brush at adjacent points. By this construc-`- tion it is unnecessary to miX` the sand and cement, provided the feed mechanisms are so proportioned as to supply sand and cement in proper proportions to the brush.

In the practical operation of the machine the sand and cement either separated or mixed, is fed to the periphery of the brush and carried around therewith within the casing, the proper quantity of water being supplied to produce a plastic mixture which will crystallize very shortly after it is discharged from the casing, the discharge tak- 1n (br ,broken lines) between the foremost plate 8 and the beveled end of the flange 3 in advance of said plate. If it is desired to discharge the material at right angles to the direction indicated in Fig. 2, the'pl'ates 8 are adjusted so as to close the part of the opening 4 which is uncovered in Fig. 2, and expose that part of said opening shown as closed by the rearmost plate 8 in Fig. 2.'

If it is desired to discharge the material between the plates they are adjusted in opposite directions so as to leave unclosed space between them. l

It is frequently-desirable to discharge material in different directions and `for this reason the adjustable plates are provided, as such adjustment can be effected with place tangentially as indicated in Fig. 2,

much less trouble and in less time than it would be possible to adjust the machine as a whole.

In the operation the machine may be moved along the length of the obj ect against which the material is plastered under the force developed by the ra id rotation of the wheel, or the object may e moved.

I claim: Y

1. rIhe combination of a casing having a discharge opening-and a feed opening and a rotary brush arranged within the casing and adapted toreceive concrete material on its periphery from, said feed opening and discharge 1t through said discharge openlng, a drlven conveyer for forcing concrete Vmaterial into the casing and against the periphery of said driven brush through said feed opening, and means for supplying water to the casing at the periphery of said brush to wet the concrete material thereon.

2., The combination of a casing having a discharge opening and a feed opening, a rotary brush arranged within the casing and adapted to receive concrete material on its periphery from said feed opening and discharge it from said discharge opening, a pair of driven conveyers, one 1for forcing sand and the other for forcing cement through said feed opening against the periphery of said rotary brush, and means for supplying water to the casing at the periphery of said brush to wet the sand and cement upon the latter,

3. The comblnation of a circular casing having a feed opening and a discharge opening, a conveyer casing communicating with the feed opening,.a hopper to supply material to said eonveyer casing, a valve-controlled pipe for supplying water to the casing through the clrcumferential Wall at a point in advance of the feed opening thereof, a spiral conveyer in the conveyor casing,

'a circular brush fitting snugly in the `cas-ing,

means to revolve said brush, and means for 'transmitting power from the shaft of the brush to the saidspiral conve er.

In testimony whereof I a X my signature, in the presence of two witnesses.
